We're dividing 123950 by 8 
Let's see how many times 8 fits into 123950.

On to step 1:
When dividing 1 by 8, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 8

On to step 2:
The number 8 fits into 12 1 times, leaving a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 8 from 12 to get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 8

Advancing to step 3:
8 can be fit into 43 5 times, resulting in a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtract 40 from 43 to get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 8

Moving on to step 4:
8 can be fit into 39 4 times, resulting in a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 154.0
The remainder is 7 after subtracting 32 from 39.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 8

Step 5:
The number 8 fits into 75 9 times, leaving a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 1549.0
Subtracting 72 from 75 leaves us with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 8

On to step 6:
8 can be fit into 30 3 times, resulting in a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 15493.0
If we subtract 24 from 30, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
If we divide 60 by 8, we get 7 and a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 15493.7
Subtracting 56 from 60 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
If we divide 40 by 8, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 15493.75
Deduct 40 from 40 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
8 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 15493.75
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
The number 8 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15493.75
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 15493.75, and the remainder is 0.0.
